I have just added a new 2008 R2 DC into my 2003 domain. The DCpromo went fine but since the reboot I cannot connect to it or ping it. Logging onto the server I see that the network is "unidentifed" and has been put into a "public" firewall profile instead of "Domain". I cant connect to anything or ping anything from the server either.
What has gone wrong?
Ive tried different NICS, disabling, enabling etc but nothing doing!
